Hi,

I've got a strange behaviour with my midi controller and/or freebob/ffado.
I made a pure data patch, with a midi learn function. So I can control everything with my midi controller.
When I use jack with Freebob or ffado (I tested both) and a Presonus Firebox, I got cracking sounds every time I move faders, pots from my Midi Controler.
When I use jack with alsa and a poor usb berhinger UCA202 it works perfectly : no cracking sounds

Is your midi controller attached to the Presonus box or is it a USB midi controller?

I tried with USB and directly attached to the Presonus. My controller is a Korg microKontrol, but I tried with another controller too (an EMU I think)
I also tried with Jackd and Jackdmp , cause I am on Gentoo 64bits.

What settings do you use for jackd?

My settings are :

/usr/bin/jackd -R -dfirewire -r48000 -p256 -n3

Thanks you for your help,
Cheers,

Mysth-R
